is not all all forms of telling your members not brain washing? you dont say "OMG WE ARE GONNA GET OWNED SO HARDCORE..oh and we totally had this coming sucks you joined us =\" no... you would say "Hey dudes this situation was just an attempt to disrupt our awesomeness and honestly and truthfulness so lets do our best and kick some $@!"
Anything any alliance says to try and inform, presuade, educate is a form of propoganda which can be called "brain washing"
